This is fork of original library with TCP-keepalive fix. Untill original package have not this fix, this package will be updated.
You can prefer to use original PG lib with standalone fix. If it is so - use pg-ka-fix
$ npm install pg
Generally you will access the PostgreSQL server through a pool of clients. A client takes a non-trivial amount of time to establish a new connection. A client also consumes a non-trivial amount of resources on the PostgreSQL server - not something you want to do on every http request. Good news: node-postgres ships with built in client pooling.
var pg = ;var conString = "postgres://username:password@localhost/database";//this initializes a connection pool//it will keep idle connections open for a (configurable) 30 seconds//and set a limit of 10 (also configurable)pg;
Sometimes you may not want to use a pool of connections. You can easily connect a single client to a postgres instance, run some queries, and disconnect.
var pg = ;var conString = "postgres://username:password@localhost/database";var client = conString;client;
To install the native bindings:
$ npm install pg pg-native
To use the native bindings, first install pg-native. Once pg-native is installed, simply replace
require('pg').native please report an issue.

We love contributions!
If you need help getting the tests running locally or have any questions about the code when working on a patch please feel free to email me or gchat me.
I will happily accept your pull request if it:
- has tests
- looks reasonable
- does not break backwards compatibility
Information about the testing processes is in the wiki.
Open source belongs to all of us, and we're all invited to participate!
If at all possible when you open an issue please provide
- version of node
- version of postgres
- smallest possible snippet of code to reproduce the problem
Usually I'll pop the code into the repo as a test. Hopefully the test fails. Then I make the test pass. Then everyone's happy!
If you need help or run into any issues getting node-postgres to work on your system please report a bug or contact me directly. I am usually available via google-talk at my github account public email address.
I usually tweet about any important status updates or changes to node-postgres on twitter. Follow me @briancarlson to keep up to date.
node-postgres is by design pretty light on abstractions. These are some handy modules we've been using over the years to complete the picture. Entire list can be found on wiki
